Since this is the only airline that we really can fly with going to Orlando I was wondering if I purchase my airfare now for our Feb-March trip of 2006 now and the fare does by some miracle go down will NW issue us a travel voucher for the difference? The price has already gone up by 10 dollars and I am afraid with the rising costs of fuel the price will even go up higher. So should I book now or should I wait until September? That is what we did last year and the prices were a little cheaper but I am not as hopeful for that this year. Any suggestions would be appreciated.
